A "Brass Union OD x NPT" fitting is a brass connector that joins two pieces of tubing or a tube and a pipe thread. It uses a compression union on one end for attaching to tubing (specified by its Outside Diameter, or OD) and a National Pipe Taper (NPT) thread on the other end for connecting to a pipe. These fittings are commonly used in plumbing, HVAC, and industrial applications. 

A Brass Equal PU Elbow is a plumbing or pneumatic fitting made of brass that allows a 90-degree change in direction of pipe or tubing flow. It's designed to connect two pieces of polyurethane (PU) tubing together, typically with a push-to-connect mechanism, making it easy to install. These elbows are commonly used in plumbing, pneumatic systems, and other applications where a right-angle connection is needed.
